In Howrah-Delhi Rajdhani route over a busy yard at Barddhaman an engineering challenge was confronted in the form of rebuilding of an existing dilapidated ROB by construction of a new 4 lane ROB. Barddhaman yard is one of the busiest yard of Eastern Railway and Rajdhani route over Barddhaman station spanning across 8 platforms and 10 tracks.
Barddhaman is situated at 107 Km from Howrah on Howrah-Delhi route. There is an old multi span ROB of brick masonry construction over the Barddhaman Railway yard, which is connecting the G.T. Road side of Barddhaman Town with Kalna-Katwa Road. The existing ROB is an extremely busy corridor carrying a large number of fast and slow moving vehicles along with pedestrian traffic. Since condition of the existing ROB is poor due to its old age, rebuilding of the existing ROB was sanctioned. A Cable Stayed ROB was the only option acceptable to Railways and the State Govt. in this very busy and electrified yard.
There are numerous constraints such as restriction of maximum height of the road surface clearances and very busy movement of rolling stock over the yard. Such constraints resulted in asymmetric cable stayed bridge of 188.429 m span with part RCC in back span, composite deck and steel pylon.
